“…Penggunaan model pembelajaran yang sesuai akan mendorong siswa untuk belajar dengan baik yang pada gilirannya akan berdampak terhadap hasil belajar mereka (Dasar, 2017;Eggen & Kauchak, 2012;Kurniati, 2017b;Sepyanda, 2017;Setiawan & Wijaya, 2022).…”

Kegiatan Pengabdian berbentuk workshop ini bertujuan untuk memberikan pelatihan kepada Mahasiswa Prodi Pendidikan Bahasa Inggris dan Guru di SD 205/IV Kota Jambi. Model yang ditawarkan penulis dalam kegiatan PKM ini adalah PBL-CG (Problem Based Learning with Communicative Games). Model ini dikembangkan dari model PBL yang terdahulu (PBL) untuk pengajaran Bahasa Inggris di Sekolah Dasar. Metode yang digunakan dalam workshop ini meliputi tiga hal, yaitu; 1)menetapkan masalah prioritas mitra, 2)justifikasi penentuan masalah prioritas, dan 3)prosedur kerja. Prosedur kerja meliputi tiga tahapan, yakni; persiapan, pelaksanaan dan pelaporan. Kegiatan workshop dilaksanakan selama dua hari bertempat di SD N 205/IV Kota Jambi. Adapun hasil dari workshop ini adalah guru-guru Bahasa Inggris SDN 205/IV Kota Jambi terlihat sangat antusias dan berjalan lancar. Materi pelatihan dapat diserap dengan baik oleh peserta terihat dengan meningkatnya nilai rata-rata peserta pada evaluasi post test. Sehingga para peserta dapat menyusun RPP Bahasa Inggris berbasis yang berbasis Kurikulum 2013 dengan menerapkan model PBL-CG dalam proses pembelajaran Bahasa Inggris di sekolah beserta rubrik penilaiannya.

Continuing previous research entitled “The Innovation of Making MAG-DAG Biodegradable Surfactants Based on Silkworm Waste: Raw Material for Animal Oil”. So this study aims to determine the kinetics of the reaction. Determining the order of the reaction can only be done experimentally, the second-order reaction is not always bimolecular, but the bimolecular reaction must be of second order. The reaction is carried out at various temperature variations namely 65°C, 75°C, and 85°C at 1 atm pressure. Each interval of one hour, samples were taken from the process up to 4 hours of reaction time, to then be analyzed the residual content of triglycerides in each sample. The results showed that the higher the reaction temperature, the faster the reaction. Further analysis showed that the reaction that occurred was an alternating second-order reaction, the deviation was respectively 8.84% and 16.71%, with the values of k1 and k2 : k 1 = 1 , 1625 × 10 5 exp ( − 6946 , 06 T ) ( L mol .s ) k 2 = 7 , 4306 exp ( − 4038 , 74 T ) ( L mol .s ) The general equation for the reaction speed of pupa oil glycerolysis is r = k1 (CA) (CB) – k2 (CC) (CD)
